Book excerpt: Of value to business people, environmentalists, and educators alike, Mid-Course Correction is a business book about the environment that's written from a personal perspective. With passion and pride, Ray Anderson, Founder, Chairman, and CEO of one of the world's largest interior furnishings companies, recounts his awakening to the importance of environmental issues and outlines the steps his petroleum-dependent company, Atlanta-based Interface, Inc., is taking in its quest to become a sustainable enterprise - one that will never have to take another drop of oil from the earth.
